Interestingly enough, while looking for that I found this clip
of when Lorena turned Bill into a vampire. She didn't even bury him. Though it does imply that they have to drink directly from their would-be sire, so I guess that's something of an answer to it.
I think we were both remembering it right. At about 1:30 of this clip you can see Bill being buried with her and then it picks up where your clip starts.
